I am looking for a mechanism that implements Proof of stake (PoS) in ethereum. I am working on a mechanism that closely related to PoS, however, I do not find any other platforms. I was hoping that Proof of Authority (PoA) somehow related to PoS but I get confused by the implementation available on the web.
If you have any knowledge and tutorials that a complete private implements similar to PoS or PoA, please help to get those information. I also have a question that in PoA, regardless of the reputation, the nodes chances to become miner is random and equally weighted?
Thanks in advance.
